Default P51 Mustang CARF "RENO Air Race" modification

Hello,

my name is Hannes Lutzenberger, I´m 30 years old and from Germany.

After a trip to the RENO Air Races 2011 and 2012 the idea was born to build a RC P51 Mustang as UNLIMITED race plane.

A few weeks ago, my buddy crashed his CARF P51. I got this plane and started to work on the plug for the turtledeck...

The plan is it to get 3x modificated P51 in the air over Germany in 2015 :-) Hope you like "our" project!


STEP 1 - the basic plane




STEP 2 - cut the canopy




STEP 3 - make a foam block




STEP 4 - put it on the fuselage

I like the concept - and I think something similar has been done before. What is broken in the P-51?

If it were mine, I'd try to think of a colour scheme that is "mine" - instead of replicating something that flew in USA.

Thank you, the fuselage was broken two times and the gear was out of the wing :-(

We will try to build replicas from STREGA, Stiletto and Precious Metal :-)

regards

A Reno Racer is an awesome choice! They are hardly modeled. There are plenty of color schemes, too. If you're going to build one then might as well go all the way and replicate the 'real deal' instead of creating some spuriously colored bird.

That´s the goal :-)

For Strega and Stiletto things are not too complicated: just pick a year and match the colors, and you are close.

There have been lots of different iterations of the Precious Metal. All of them look great. The recent ones have the Griffon engine, so you'd need to make the nose more bumpy. For something different, a 1975 or 1977 Precious Metal could be good. Photos show it with a Merlin and it has a lower version of the normal bubble canopy. in 1977 it already had a taller fin.

We will build Precious Metal from 2012

I like the method to build reinforcement onto the mold. After gel-coat it looks like you soak glass matt in resin then just lay it in place... correct?

Today the fiber glass delivery arrived! Looks like to be a long weekend, because we have to make three P51 turtledecks :-)

Very cool project. Looking forward to the video of them flying together! Wait, are the three racers going to fly together? Lol

Quick question, why does the Gotha wing need to have the thrust tube extensions?
Ive seen this before but nobody has answered why this is needed.

Nice work!

Horten rather than Gotha. I've often wondered the same and would be interested in the answer as well. Is it a thrust efficiency issue?

Ok, Horten Ho IX / Ho 229, Invertmast built his own and also had the extensions but didnt go into why they are this way. There must be a relationship between the exhaust exit distance from the CG or something, wish I could see this in action in person, pretty interesting.

Is there a good thread on this somewhere that we can read?

Sorry, derailed the thread...

Looks like a well done project. Best of luck getting them finished and flying.

Pretty lady in your pic.
